I moved this to the Warzone section. For Chronopia, there is always a wound on a 1. For Ultimate Warzone, which is the edition played around here, a 1 is a critical hit, and you add, I believe, 3 to the damage of the attack.
I'll let the Warzone illuminati around here help you more, as many of them have played all the editions of the game.
Cheers.
